Experimenting with a dangerous all-syrup Squishee, Bart and Milhouse get loopy and run around Springfield singing and having adventures. Waking up with a massive Squishee hangover, Bart remembers that he enlisted in the Junior Campers, the dweebiest after-school program in the world. Bart is prepared to quit the group, but decides to stay when group leader Ned Flanders leads a lesson on using a pocketknife. Bart becomes entranced by Junior Camping, attending meetings and becoming an expert at tying knots. When it comes time for the annual Junior Campers' father and son rafting trip, Bart is too embarrassed of Homer to invite him along. Homer comes anyway, and his terrible navigation and rowing skills land Bart, Ned and Todd way up a creak with no way home. Luckily, Homer saves the day when he's able to smell out a nearby Krusty Burger franchise.
